GATE.

CPE CIPICATIOII f lining part of Letters Patent. No. 327,653, dated October 6, 1885.

Application filed April 15,1885.

1"0 aZZ whom it may concern.-

Be it known that I, J AMES N. BUCKNER, of Vindsor, in the county ofv Essex and Dominion of Canada, have invented new and useful Improvements in Gates; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in that class ofgates which are adapted to be opened and closed by the passage through them of a wagon or carriage, which, coming in contact with the mechanism upon one side of the gate, causes the same to open, and after passing through, coming in contact with the other similar mechanism, causes the gate to close without the necessity of operating the gate by hand.

The invention consists in the peculiar construetion of the various parts and their combinations, as more fully hereinafter described.

In the accompanying drawings, which form a part of this specification, and in which my invention is shown in perspective, A, B, and 0 represent what may be termed the gateposts, their upper ends being connected by means of a girt, D, secured thereto. Pivotally and centrally of its length, by means of a bolt, a, or other suitable device, is secured the track E. F is a bracket supported by the girt D over the center of the gate-opening G, and Iis a lever of which the bracket F forms the fulcrum, and the outer end of this lover I is secured by means of thelink H with the track E. The opposite end of this lever is connected by means ofa wire cable, J, or its equivalent,to a horizontal arm, I), of the four-armed bell-crank K, which is centrally and pivotally secured to the post B near the ground. To a vertical arm, 0, of this bell-crank is pivotallysecured the connecting-rod L, the opposite end of which is sleeved upon the crank-arm M, which forms an extension of the bale N, which is secured to a bed-plate by means of eyes or hooks d. One end of a spring, 0, is secured to a post, I, or through a suitable device driven into the ground, while its opposite end, by means of the chain Q,is pivotally secured to the crank M. R is another bracket supported upon the girt D, and operates as a fulcrum for the lever S, the outer end of which is connected by means Serial No. 162,297. (Xe model.)

of this link T with the track E, while the opposite end of this lever, by means of the cable J, is connected with a horizontal arm, I), of

the crank K, and a vertical arm, 0, of this crank, by means of the connecting-rod L, is connected with the crank M, which is formed by the prolongation of the bale N, which is secured to a bed-plate by means of the eyes d. O is a spring, one end of which is secured to a post, P, or other suitable device laid into the ground, while the other end of such spring, by means of the links or chains Q, is secured to the crank M.

In the drawings the gate is shown as closed. A person driving toward the gate to pass through the same guides the off front wheel of his vehicle to cause it to strike the bale N and throw the same down from its vertical to a horizontal position toward the gate. The effect of this is to raise the end of the tilting track 11 from its resting place upon the stop U, and compel it to tilt in the opposite direction until its opposite end rests upon the stop U. Now, the gate V being hung upon such track by means of the hangers and grooved wheels \V, it will run down the inclined plane until it strikes against the stop X, which consists of a small friction-roller secured in a bracket to the post 0. The gate now being open, the carriage is driven through until the wheel strikes the bale N, which compels the track to resume its original position, when the gate will again travel down the inclined plane until it strikes the stop X similar to that already deseribcd and attached to the post A.

It will be noticed that the horizontal arms b b of the crank K to which to attach the cables J and J, and that the stops U and U,arc adjustable by aseries of holes, and by chang ing the cables from one hole to another in the crank, and the stops from one hole to another in the supports therefor, the degree of inclination of the track may be varied.

It will also be noticed that the crank M is shown in dotted lines in one of the figures. This is merely to show that the position of the crank may be reversed from that shown and described, if it is desired-so to do, in order to inclose this portion of the device in a box to protect it from snow.

I am aware of the Patents Nos.14,851, 31,435, and 81,569, and make no claim to the eonstructions shown therein as forming part of my invention.

What I claim as my invention is 1. The combination, with a gate-frame and a track centrally pivotedto the crossgirt thereof, of two levers pivoted upon said girt and connected with opposite ends of said track, two bails, each having a crank and arranged in the road-bed, one on each side of the gate, the bell-crank K, pivoted to the center post, B, the cords J J, connecting the inner ends of said levers With the bell-crank, and the rods L L, connecting said bails with the bell-crank, substantially as and for the purposes specified.

2. The combination, with a gate, a gate-frame consisting of the posts A B O and girt D, and a track, E, pivotally and centrally secured to said girt and supporting the gate, of the adjustable stops U U, links H T, levers I S, crank-lever K, and cables J J, adjustably secured thereto, substantially as and for the pur poses specified.

3. In combination with a gate supported by means of wheels running upon an overhung 'of, four-armed lever K, pivoted to the central post of the gate-frame, the cables J J, connecting two arms of said lever K with the inner ends of said levers I S, bails N N, connected to the other arms of the lever K, and carrying cranks, the springs 0 o, and chains QQ, connecting the same with the cranks, substantially as and for the purpose specified.
